• How is soybean oil extracted in a continuous and countercurrent process?
  • Extraction of soybean oil in a continuous and countercurrent process. Multistage extraction was experimentally reproduced from batch single-stage assays. The process efficiency was mainly limited by the oil solubility in the solvent. The minimum solvent mass flow and the number of ideal stages were calculated.
  • Which solvent is used in soybean oil production?
  • Solvent extraction and expelling are the main processes used in soybean oil production. Hexane is currently the leading solvent in extraction , . This solvent has a high solubility for oil extraction, availability, low price, low boiling point, and heat of vaporization .
  • How is oil extracted from soybeans?
  • Due to the moderate oil content (18 ¨C 23%mass) , it is mandatorily recovered from soybeans by solvent extraction . Currently, industries adopt a continuous-countercurrent-multistage extractor for oil extraction from vegetable oilseeds.
  • What is deodorization in soybean oil production?
  • Deodorization removes free fatty acids and volatile compounds from the feedstock . Solvent extraction and expelling are the main processes used in soybean oil production. Hexane is currently the leading solvent in extraction , .
  • Which terpene is best for soybean oil extraction?
  • Oil extraction yield is more significant when using terpenes, CPME, and 2-MeTHF. In contrast, some advanced technologies such as enzyme-assisted, supercritical fluids, deep eutectic solvent, and ionic liquids seem less efficient than ordinary processes using hexane for soybean oil extraction.
  • Which model is best for soybean oil extraction?
  • In a general conclusion, it can be affirmed that the empirical So and Macdonald model is the best model to describe the soybean oil extraction, followed by the mass transfer kinetic model when correctly used. The typical values for the mass transfer parameters found in the literature for soybean oil extraction are presented in Table 7. Table 7.
